As a preview of their halftime show at Super Bowl XLIV, The Who's Roger Daltrey and Pete Townshend played a brief acoustic set Thursday for a room full of reporters at the Ft. Lauderdale Convention Center.

With other appointments to make, they hustled out of the convention center shortly after the performance. Awaiting outside was a clutch of autograph hounds, likely a mix of Who fans and professional memorabilia dealers. As Townshend emerged from the building, escorted by handlers and guarded by sheriff's deputies, the autograph-seekers called to "Mr. Townshend."

Without cracking a smile or uttering a word, he made his way over to them, scrawled his mark on a variety of photographs and album covers, and then disappeared into a waiting sedan.
